Overview
ARV ODESHOG is a municipal wastewater treatment plant serving Ödeshög, Sweden. It treats wastewater from approximately 6,500 people and discharges into the local watershed.
ARV ODESHOG is a municipal wastewater treatment plant located in Ödeshög, Östergötlands län, Sweden. The plant serves a population of approximately 6,491 people, classifying it as a small to medium agglomeration under Swedish and EU regulations. As a Swedish facility, ARV ODESHOG operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 volume unit, and it is situated within 50 km of the coast, indicating potential sensitivity to nutrient discharges. The treated effluent from ARV ODESHOG is discharged into the local water system, which ultimately drains into the Baltic Sea. The Baltic Sea is a brackish water body with limited water exchange, making it sensitive to eutrophication from nutrient inputs. The plant's location in a coastal region underscores the importance of effective treatment to protect downstream marine ecosystems.
Environmental context
ARV ODESHOG discharges into the local watershed, which drains into the Baltic Sea via the Motala Ström or nearby rivers. The Baltic Sea is a semi-enclosed brackish sea with slow water renewal, making it highly sensitive to nutrient pollution. The plant's proximity to the coast (within 50 km) means its effluent can contribute to eutrophication, affecting algae blooms and oxygen levels in coastal waters.
